That’s probably what IHOP had in mind when it tweeted about the holiday this morning. But things quickly got a lot weirder.

“If you have pancakes in your tum tum, does that make you a pancake mum mum? Happy Mother’s Day to ALL the mums out there!” the pancake chain wrote, attaching a photo of an ultrasound with a ghostly stack of pancakes visible.

IHOP’s marketing strategy of late has been described as “bold”. It included, for instance, temporarily rebranding to the “International House of Burgers” last year, which the company said caused burger sales to quadruple.

The company did not immediately respond for comment.

It’s not the first time that the two organs have been confused. In 2015, an Idaho lawmaker made headlines after asking a physician expert a question implying that the stomach and uterus were connected. (The lawmaker has said he was trying to make a rhetorical point.)

But it’s possible someone could believe that, author and sexual health expert Martha Kempner said in a Rewire article at the time.

“After all, most of us are told as children that we grew in our mummy’s ‘tummy’,” Kempner wrote. “Unless that oversimplification is corrected either by our parents or a sex ed class, misunderstandings can easily remain.”

A woman’s belly does protrude out during pregnancy. That’s because the uterus expands out over the 40 week period to accommodate a growing foetus, pressing on organs like the stomach in the process.

I’m no expert on anatomy but I’m pretty sure pancakes never make a trip there during the digestive process https://t.co/ON7jxgagC9
